Crested Gecko Care Guide
Is a crested gecko right for you?
Crested geckos are some of the easiest reptiles to care for. They're nocturnal so they don't need basking heat, they eat a commercial diet so daily insect feeding is optional, and they tolerate room temperatures across most US homes. Excellent first reptile for an apartment.
The catch: heat sensitivity. Crested geckos can die from sustained temperatures above 82°F — Arizona, Texas, and Florida summers without AC are a real risk.
Size
Adult crested geckos reach 6-9 inches in total length and 35-55 grams. They're small. Hatchlings are about 2-3 inches.
Lifespan
15-20 years in captivity. Many will outlive their first owner's college years and into the working career.
Enclosure
Minimum adult enclosure: 18" × 18" × 24" tall (45 × 45 × 60 cm). Height matters more than floor space — crested geckos are arboreal. Standard glass terrariums work well; front-opening designs preferred.
Decoration: cork bark slabs, sturdy branches (oak, dragonwood, manzanita), broad-leaved live or artificial plants (pothos works and is non-toxic). Build up vertical climbing structures. Substrate: coco fiber + sphagnum moss for naturalistic setups, or paper towel for hatchlings until they're feeding reliably.
Temperature
- Day: 72-78°F (22-26°C)
- Night: 65-72°F (18-22°C)
- Maximum tolerated: 82°F (28°C) sustained — over this is dangerous. Spikes above 85°F can be lethal.
Heat is rarely needed if room temperature stays in the comfort range. If supplemental heat is required (cold homes in winter), use a low-wattage halogen on a thermostat with a clear ambient temperature target — NOT a basking lamp.
Humidity
60-80% target, with daily cycling. Mist heavily at night to bring humidity to 80-90% briefly, allowing the enclosure to dry to 50-60% during the day. Constant high humidity (no dry phase) leads to bacterial and fungal problems.
Diet
Crested geckos eat commercial powdered diet mixed with water (called CGD — Crested Gecko Diet). Three major brands are accepted: Pangea (a standard), Repashy Superfoods (Grubs'n'Fruit, Sun-Fire formula), and Black Panther Zoological. Rotate flavors for variety.
Mix 1 part powder to 2 parts water; offer fresh every 1-2 days, removing uneaten food before it dries.
Insects (crickets, dubia roach nymphs) can be offered weekly as enrichment but aren't required when a good CGD is the staple. Dust insects with calcium if offered regularly.
Don't feed: mealworms (low nutrition), waxworms as a staple (too fatty), fruit baby food (insufficient calcium).
UVB
Optional. Low-output linear T5 UVB (Arcadia ShadeDweller) supports vitamin D3 metabolism in addition to dietary D3 in CGD. Recommended but not strictly required if a good CGD with proper D3 is the staple diet.
Handling
Crested geckos tolerate gentle handling but are jumpy and athletic. Handle close to soft surfaces (over a bed or sofa) until you know the animal's behavior. They can jump unexpectedly. Don't grab the tail — they autotomize (drop the tail) and crested gecko tails do NOT regenerate, unlike many other geckos.
Common health problems
- MBD: From insufficient calcium-with-D3 in diet, often from offering inadequate alternatives to a complete CGD.
- Floppy Tail Syndrome: Pelvic deformity from inadequate climbing structure (gecko sleeps head-down on glass for years). Provide proper vertical perches.
- Impaction: From inappropriate substrate or oversized prey.
- Tail loss: Stress response; tail does not regrow. Avoid stressors.
- Heat stress / death: From temperatures above 82-85°F.
Common crested gecko mistakes
- Letting temperatures spike in summer. Check the enclosure temperature on hot days. AC, fans, ice packs in a pinch.
- Skipping CGD for fruit baby food. Causes calcium deficiency and MBD.
- Grabbing the tail. It will drop. It will not grow back.
- Tall narrow enclosure with no horizontal branches. The animal gets pushed to sleep on glass, causing Floppy Tail Syndrome.
- Constant humidity with no dry phase. Leads to skin infections. Mist heavily then let it dry.
- Cohabiting two males. They fight.
